Abstract
Method and apparatus for developing and recording information relating to the color present in a scene under certain illumination conditions. The developed information may be analyzed and compared against certain standards and adjustments made either before or after the scene is recorded on color film to maximize fidelity of the color reproduction during the processing of negatives and prints from said film. An optimized exposure correction is provided for any given set of specific primary spectra of each film layer sensitivity and print dye component for a preferred set of test colors.
